Electromagnetic torque will be present like in synchronous generator.Aditya Kumarhttps://www.blogger.com/profile/12703320786970627241noreply@blogger.comtag:blogger.com,1999:blog-7150175436311719447.post-51595351535402904652018-02-14T07:50:24.516-08:002018-02-14T07:50:24.516-08:00SIR FOLLOWING IS A QUESTION IN &quot;JB GUPTA ELEC...SIR FOLLOWING IS A QUESTION IN &quot;JB GUPTA ELECTRICAL QUESTION BANK&quot;<br /><br />A rotating electrical machine having its self inductance of both stator and rotor winding independent of its rotor position will definitely not develop:<br /><br />1. SYNCHRONISING TORQUE<br />2. RELUCTANCE TORQUE<br />3. STARTING TORQUE<br />4. HYSTERESIS TORQUE<br /><br />and the answer given is synchronising torque but after reading your blog i think answer should be RELUCTANCE TORQUE as dL/d0 will be zero so no reluctance will be present.<br /><br />Please explain Sir.Anonymousnoreply@blogger.com
